On July 18, 1927, Athletics outfielder Ty Cobb became the first major leaguer to collect his 4,000th career hit. Cobb hit a double off his former Tigers teammate, Sam Gibson, at Navin Field in Detroit. The hit came in the first inning of a 5-3 loss for the A’s.
Cobb retired after the 1928 season with 4,191 hits, a record that will stand until Pete Rose breaks it in 1985.

wrapping my head around 4,000 hits in one career is hard especially when i think of it as 20, 200 hit seasons. I think I have the math right?
You do! And wow, I hadn’t thought about it that way. That certainly puts it in perspective.
